Well Frank and I , mostly Frank, pulled the heads off my car. No visible damage to the heads or cyclinder walls. So tomorrow I can pull the engine apart after I pull whats in the car out. All I came up with so far is way to much piston to wall clearance. How much I really dont know yet. Its always fun when you own a S.C. I got a whole 3000 miles on this engine. May as well put in a bigger cam and do some more head work. After all its going to be apart. Maybe I can get 3500 miles out of the next rebuild. Tim
